What it is

GPUImage for Android is a GPU-accelerated image filtering library that ports the iOS GPUImage framework to Android using OpenGL ES 2.0. It provides 50+ real-time filters (sepia, blur, edge detection, blend modes, etc.) that run on the GPU via shared vertex and fragment shaders, enabling high-performance image processing on Android 2.2+ devices. Single library module structure: library/src/main/ contains Java filters under jp/co/cyberagent/android/gpuimage/filter/ (50+ GPUImage*Filter classes), core rendering logic in GPUImageRenderer.java and GPUImage.java, and native YUV decoding code in C (cpp/yuv-decoder.c). Filters extend shared base classes like…

Start here

Open these first:

  • library/src/main/java/jp/co/cyberagent/android/gpuimage/GPUImage.java — Main public API entry point; orchestrates filter application and rendering lifecycle.
  • library/src/main/java/jp/co/cyberagent/android/gpuimage/GPUImageRenderer.java — Core OpenGL rendering engine; handles GPU texture pipeline and frame rendering.
  • library/src/main/java/jp/co/cyberagent/android/gpuimage/filter/GPUImageFilter.java — Abstract base class for all filters; defines shader compilation and parameter binding contract.
  • library/src/main/java/jp/co/cyberagent/android/gpuimage/GPUImageView.java — Android View wrapper for GPU rendering; bridges UI lifecycle to renderer thread.
  • library/src/main/cpp/yuv-decoder.c — Native C code for YUV format decoding; critical for camera input performance.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone: git clone https://github.com/wasabeef/android-gpuimage.git && cd android-gpuimage. Install: Ensure Android SDK is available; Gradle wrapper is included (./gradlew on Unix, gradlew.bat on Windows). Build: `.…

Daily commands:

No standalone app server—this is a library. To test: integrate into an Android activity (see README snippets), call GPUImage gpuImage = new GPUImage(context), attach a GLSurfaceView via setGLSurfaceView(), load an i…

Key cautions & unknowns

  • Stale — last commit 4y ago
  • Concentrated ownership — top contributor handles 55% of recent commits
  • No CI workflows detected
  • JCenter deprecation: The build.gradle references JCenter (marked for closure May 1st) in allprojects.repositories and has commented-out Bintray plugins—migration to Maven Central only may be incomplete in older…
  • License evidence is incomplete or ambiguous.
  • Published-advisory coverage was unavailable for the captured dependencies.
  • Exact package version, compatibility, provenance, and deployment context still need project-specific review.
